There’s something instantly off about most AI-generated portraits: the skin. Too smooth, too perfect—almost plastic. For all the astonishing progress in generative tools like Midjourney, Imagen 4, and Flux, replicating the subtle textures of real human skin remains one of the toughest challenges in the field.

This isn’t due to a lack of computational power or creative intent. Instead, it stems from how these models are built. During the diffusion process, AI is trained to remove what it sees as "noise." But human skin, with its pores, tiny blemishes, and organic imperfections, often gets filtered out right along with it. The result is portraits that look synthetic and airbrushed, lacking the depth and realism that creatives demand.

In this video, Sirio will explore how to generate portraits with natural-looking, imperfect skin. You’ll learn techniques to guide AI toward more realistic results, how to upscale images for high-resolution output, and how to prepare them for professional use—whether in print, on billboards, or in ultra-detailed digital campaigns.
